, INSULATION FOR PIPE FITTINGS Application filed November 14, 1927. Serial 1T0; 232,993. I

My invention relates particularly to formed insulation for pipefittings of various kinds and has for one of its primary objects the construction of such insulation in a manner which 5 will permit the same to be used with various types or makes of fittings and Which will accurately center the insulation for assembly purposes.

One of the important features of my invention is the provision of an inwardly extending flange or ring on the insulation which will act as a centering guide therefor on the pipe to which the fitting is joined and will also act as a locating point for such insula- 15 tion as is placed on the pipe.

With the above and other objects in view, my invention consists in the arrangement, combination and construction of the various parts of my improved device, as described in the specification claimed in my claims and shown in the accompanying drawing, in which:

Fig. 1 is an elevation showing in assembled position the two halves of an insulation ele- 535 ment for an elbow fitting.

Fig. 2 is a view taken on line 22 of Fig. 1.

Fig.3 is aview similar to that of Fig. 2

with-the addition of the elbow fitting and its pipe connections as well as the insulation 3 for the pipe connections, such insulation being shown in section.

Fig. 1 is a view taken on line 1- 1 of Fig. 2. I have shown a pair of insulation members 5 and 6 which are identical in form and which may be placed together as shown in Fig. 2 to form a complete enclosure for an elbow fitting. I

As will be particularly seen in Fig. 2 the inner bearing face of each insulation member resembles in formation an elbow fitting. I have provided transversely extending curved grooves? and 8 in the insulation for the purpose of receiving the flanges 9 and 10 of an elbow fitting. I have also provided a central depressed portion or longitudinally ex- PATENT; OFFICE tending curved groove lllwhich. is approximately atthe intersection of the longitudinal and transverse center: lines of the'insula-. tion" and serves to make possible the use of the insulation member on lvarious types of 'fittings. -That is to say, the insulation may be used on either .castor malleable fittings and 1 willconform to the shape of fittings made by different manufacturer's. The bearing face of the insulation at the inner'corner of the same is arched as at 12 so that it may-bean on the body of the heavier types of castfittings sold by some manufacturers. i 7

In order to definitely locate the insulation during assembly, I provideeach half with a pair of inwardly extending flanges 14 and 15, which flanges are adapted to mate with flanges on the other insulation member-to form a continuous ring whose innerbearing surface contacts againstthe pipes 16 and 17 which arefsecured inthe elbow'fitting 18 and which are held to relatively close'limits by all manufacturers! The sides of the'flanges adjacent the fitting-18 co-operate with the ends thereof at'19and'20'to locate the insulation relative to the ends of the fitting. 1

The other sides of the flanges 14 and 15 act as stops or-locating points'22 for the insulation 21 shown in the lower end ofthe insulation for the fitting in Fig: 3, which insulationis received within the extended end 24; of the fitting insulation and is squeezed into'contactwith the pipe 16by the inner tapered walls to hold the insulation 21'together and prevent a circulation ofair through the joint between the same and the fitting insula tion'." Wheres; thicker pipe insulation such as 23 is-employed, it mayabutagainst the ex? tended endQl of the fitting-insulation as" shown in the up er part orri 13, and strap 8 such as 26 may be'exten'dedj around tlie' joint to hold both halves" of thefitting' insulation and the pipe insulation togethefand inplace, as well as to seal the joint between the same against the circulation of air; At the sanie fill I groove in the depressions.

sulation with them.

It Wlll be apparent that when malleable and the smaller types of cast fittings are used, the only points of contact between the insulation halves 5 and 6 and the fitting l8 and pipes 16 and 17 may be where the flanges 14: and 15 contact against the pipes 16 and 17, and in such case the remainder of the halves 5 and 6 will be spaced from the fitting 18. This feature is not detrimental to the effectiveness of the insulation as in such case a dead air space is formed between the fitting l8 and the inner surface of the halves 5 and 6, any circulation of air in the same being prevented by the joint between the'flanges 14 and 15 and the pipes16 and 17..

It will be apparent that when the two insulation members 5 and 6 are placed together and cemented or otherwise united, a unitary insulation structure is provided which may be easily and quickly assembled by unskilled labor and which will provide a universally formed insulation ofornamental appearance. It will be readily understood that the insulation may be applied to other types of fittings and'that'the illustration of the same applied to an elbow fitting is only one form of my invention. It will be obvious that various'changes may be made in the arrangement, combination and construction of the various parts ofmy improved device without departing from the spirit of my invention and it is my intention to cover by my claims such changes as may reasonably be included within the scope thereof.

What I claim is: V

1. Fitting insulation comprising a pair of members'ha-ving depressions therein adapted to mate and enclose a fitting, said members each having a curved groove therein extending lengthwise of the depressions.

2. Fitting insulation comprising a pair of members having depressions therein adapted to mate and enclose a fitting, said members each having a transversely extending curved 3. In combination, a pipe having a fitting thereon, insulation enclosing the fitting and having an inwardly extending flange centering on the pipe, said flange being adjacent to but inwardly of one end of the insulation, and further insulation on the pipe having an end located on the said centering flange and enclosed-by the end of said first insulation. a v v 1 4. In combination, a pipe having a fitting thereon, insulation enclosing the fitting .and having an inwardly extending flange centering fon-the pipe,. a nd further insulation on the pipe having an end located on the said centering flange, said first insulation having CLARENCE STANLEY MORGAN.
